Tunley Environmental’s LCA and EPD services at a glance

Who they are and where they work

Tunley Environmental is a UK‑based sustainability consultancy with a remote team and a U.S. company registered in Chicago. Their contact page lists Leeds as the base and shows global operations with UK and U.S. phone numbers. (contact). citeturn1search0

Core services for manufacturers

Tunley markets full‑service support for Environmental Product Declarations, including scoping, life cycle assessment, drafting, and coordination of third‑party verification. See their EPD consulting page for the end‑to‑end pitch and FAQs. (EPD consulting). citeturn0search1

They also advertise LCA as a standalone product‑level study that follows international standards and includes guided data collection and in‑house modeling. (LCA service). citeturn0search3

For broader carbon accounting around products, services, and projects, they outline footprinting offers that sit alongside LCA and EPD work. (Product and project footprints). citeturn0search6

EPD workflow, verification and PCR guidance

Their materials explain the role of Product Category Rules and indicate a preference for publishing with The International EPD System while stating they can work with other program operators. They also note use of SimaPro for impact assessment and cover categories beyond climate, such as eutrophication and biogenic carbon. (EPDs overview). citeturn0search0

What this usually means in practice. Expect a discovery call, a defined scope and boundary, a data request for a reference year, and several working sessions to validate assumptions. Traditional consultants commonly rely on structured questionnaires, spreadsheet templates, and recurring check‑ins to assemble utility data, bills of materials, and supplier information. Tunley’s contact flow describes assignment of a dedicated scientist and regular updates, which tracks with that model. (contact). citeturn1search0

Tools and software

Tunley states that it uses SimaPro for LCA modeling and formatting results for EPD publication. They point to ISO 14040 and 14044 alignment and mention third‑party verification prior to publication with a program operator such as Environdec. (EPDs overview). citeturn0search0

Sectors and typical use cases

The firm positions its offer strongly toward manufacturers and the construction ecosystem. It highlights service pages for sustainable manufacturing and for construction, each pairing product LCAs and EPDs with adjacent offers like embodied carbon assessments and supply chain work. (Manufacturing) and (Construction). citeturn0search4turn0search8

They also reference whole‑life carbon assessments for projects in line with RIBA and GLA guidance. While WLCA is a project service rather than a product EPD, manufacturers that sell into UK projects will encounter it in specification conversations. (WLCA). citeturn0search7

Timelines and effort: what to expect

Market experience suggests multi‑month schedules for a first EPD when data is dispersed across plants and suppliers. Program operators typically require third‑party verification and most EPD programs set validity at 5 years, which is useful for planning renewal cycles. (EPD International, 2024) (EPD International, 2024).

Manufacturers should plan for internal effort. That often includes pulling a year of production and utility data, clarifying system boundaries and allocation, and attending working sessions. Many teams today expect low‑friction data intake and faster turnarounds, yet the legacy consultant model still leans on spreadsheets and meetings. If your operations team is already stretched, budget time accordingly so the process feels as seemless as possible.

How Tunley frames deliverables

From their pages, the deliverables typically include an LCA model and report, an EPD draft aligned to the product’s PCR, and coordination with an independent verifier and the chosen program operator. Teams also receive reduction recommendations linked to the modeled hotspots. (EPD consulting) and (EPDs overview). citeturn0search1turn0search0

Geographic focus and fit

Tunley lists a UK base with U.S. presence and a global client map. That makes them a practical consideration for UK and European manufacturers and for U.S. firms that prefer a consultant with both UK and U.S. contacts. (contact). citeturn1search0

For teams selling into the EU, remember that corporate reporting pressure is rising. The Corporate Sustainability Reporting Directive is expected to cover about 50,000 companies, which increases requests for product‑level disclosures that tie back to LCA and EPD evidence. (European Commission, 2024) (European Commission, 2024).

Competitors in the same lane

Manufacturers comparing mid‑sized, consultancy‑led EPD and LCA support in the UK and Europe will often evaluate alternatives such as Anthesis, Ricardo, Carbon Trust, ERM, Ramboll, Sphera Consulting, Quantis, and RSK Group. These firms vary in size and software usage, yet the working style is similar: scoped projects, workshops, manual data requests, and scheduled verification.

Smart buyer questions

Before engaging any consultancy, ask pointed questions that shorten the path to a publishable EPD.

1. Which PCRs do they propose and why are those aligned with your competitive set
2. Which program operator will they target and what is the verifier’s typical review cadence
3. How will data be collected from plants and suppliers and what systems can they integrate with
4. Which LCI databases and software will be used and how are data gaps handled
5. What is the plan for multi‑plant, multi‑SKU portfolios and renewal scheduling across the 5‑year validity window (EPD International, 2024) (EPD International, 2024)

Bottom line for manufacturers

Tunley Environmental presents a conventional, science‑forward consulting offer for LCA and EPD creation, including PCR selection, modeling with SimaPro, and coordination with third‑party verification for publication. Teams should budget time for structured data pulls and recurring calls. If you want the work to move quickly and with less internal lift, set that expectation upfront and evaluate partners on their data‑collection approach, not just their LCA credentials.
